python types as tuples and reduce

I find it interesting how things can be expressed in terms of tuples in python
>>> list(( dict( ( ("a",1), ("b", "abc"), ("c", list( (1,2,3) ) ) ) ), ))
[{'a': 1, 'c': [1, 2, 3], 'b': 'abc'}]

reminds me of cons a little

so now if I break this further I can get:

>>> ( list, ( dict, ( list, ( ("a",1), ("b", "abc"), ("c", list, (1,2,3)) ) ) ) )
(<type 'list'>, (<type 'dict'>, (<type 'list'>, (('a', 1), ('b', 'abc'), ('c', <type 'list'>, (1, 2, 3))))))

and then rebuild this with possibly some sort of a reduce, such as

>>> reduce(lambda acc, x: acc +[x], (1,2,3), [])
[1, 2, 3]
